Unable to install Inventory 8.6 RU2 plug-in

• Inventory Solution

Issue/Introduction

This is the situation that the customer has reported:

1. The customer upgraded to 8.6 RU2 recently.
2. He is trying to setup new client machines by sending the usual installation policies for the desired plug-ins.
3. Everything goes smoothly until it is the turn for the Inventory plug-in (8.6.3268 version) task to install. It runs and the customer gets a "run failed" status. This is happening just to some client machines.
4. If we run the Inventory plug-in MSI manually, it installs just fine. 
5. The agent logs (attached here with verbosity turned on as well) show things like these (the customer cloned the Inventory plug-in install policy twice just to make sure it was not something wrong with the first one):

6. The "log.txt" generated (usually under "C:\Program Files\Altiris\Altiris Agent\Agents\SoftwareManagement\Software Delivery\{5864027D-DA99-4430-9183-4EFF8B362383}\cache") when the install batch runs says the following:
 
started "Symantec_InventoryAgent_x64.msi" installation
started setting variables
stopped setting variables
started setting INV_AGENT_PATH
INV_AGENT_PATH = ""
started MSIEXE /i command
stopped MSIEXE /i "Symantec_InventoryAgent_x64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1 command, error code = 1
exiting
Final error code = 1
 
7. If we run the following on a command prompt, the Inventory plug-in installs just fine:
  MSIEXE /i "Symantec_InventoryAgent_x64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1 
 

Environment

ITMS 8.5, 8.6

Cause

The problem is in the installation BAT file (InstallInvAgent.bat usually under "C:\Program Files\Altiris\Altiris Agent\Agents\SoftwareManagement\Software Delivery\{5864027D-DA99-4430-9183-4EFF8B362383}\cache" on the client machine or under the original package: "C:\Program Files\Altiris\Notification Server\NSCap\bin\Win64\x64\Inventory\Agent Package"). The installation itself finishes just fine, it is the script that passes the incorrect exit code.

Resolution

This issue has been reported to our Broadcom Development team. A fix has been added to our ITMS 8.6 RU3 release.

A workaround is to replace the original InstallInvAgent.bat with the attached one in this article and try manually to install the Inventory plug-in (just to make sure it works for you on those specific machines):

1. On the client machine, go to <\Program Files\Altiris\Altiris Agent\Agents\SoftwareManagement\Software Delivery\{5864027D-DA99-4430-9183-4EFF8B362383}\cache
2. Copy the "Symantec_InventoryAgent_x64.msi" and save it in a different folder of your choosing. 
3. Place the attached "InstallInvAgent.bat" on the same directory as the "Symantec_InventoryAgent_x64.msi" 
4. From the command prompt, navigate to the directory where you placed the files from steps 2 and 3. Run the following command:
   
   InstallInvAgent.bat "Symantec_InventoryAgent_x64.msi"
   
   
5. Check that the Inventory plug-in got installed (you can see that under the "Agent Settings" tab on the Agent UI).
